Abstract: ABSTRACT OF THE DISCLOSURE         A portable data carrier comprises at least one minia-turized circuit having several memory sections, means for trans-ferring data between the carrier and a data transfer device man-ual setting means on the surface of the carrier for presetting program elements in the miniaturized circuit, a display window fox displaying data in humanly readable form, a first single button for placing an n- digit decimal number into a first variable memory section of the miniaturized circuit, and circuit means for enabling an operator to effect this operation while re-ceiving visual feedback from the display window.  The carrier can serve as a long-life multiple account pay token. The pur-pose of producing a long-life multiple account pay token is gradually to reduce the demand of coins and bank notes thereby lowering the high cost of minting and printing them. In parallel therewith, the relatively high cost of operating cheque accounts by Banks shall be reduced.

Abstract: OFFSET-NULLED SAMPLE-AND-HOLD AMPLIFIER            Abstract A high performance operational amplifier 12 circuit 10 nulls the offset voltage by means of switched capacitors (C2, C3) and holds the signal output 18 during the nulling.  Switching is in response to two non-overlapping pulse trains ?1, ? 2.  During an output valid phase ?1, with the signal input source connected to the inverting input 14 of the amplifier 12, an offset voltage storage capacitor C2 is connected between the non-inverting input 16 and ground.  A signal storage capacitor C3 is connected between the output 18 and ground.  During a nulling phase ?2, the signal storage capacitor C3 is disconnected from ground and connected between the output 18 and the inverting input 14.  The previously grounded side of the offset voltage storage capacitor C2 is switched to the inverting input port 14.  The non-inverting input port 16 is grounded.  The offset storage capacitor C2 charges to the input offset voltage, while the inverting input 14 is reset to virtual ground.  When the circuit 10 is reconnected in the ?1 valid output phase, the offset is compensated by the input offset storage capacitor C2 without the output 18 having been directly connected to the inverting input 14.  This makes possible a shorter settling time.          Also disclosed as optional is an output offset limiting feedback network 35 for preventing a locking of the circuit 10 which can result from excessive initial offset voltage and a capacitor C4 connected between the input side of the signal hold capacitor C3 and the inverting input 14 to prevent sensitivity to clock leakage.

Abstract: CORRELATION TYPE FLICKER FLAMON            ABSTRACT OF THE DISCLOSURE            A device and method is disclosed which determines the presence and absence of a burner flame by injecting a pressure moduluted signal into the burner which modulates a flame at a selected frequency.  Light emitted from the flame is modulated at the same frequency.  An optical sensor is provided for sensing the light amplitude modulation frequency and connected to a correlator circuit for correlating the light amplitude modulation signal with the pressure modulation signal.  If the signals correlate, a flame is assumed to be present and a flame on signal generated.  The pressure modulation signal can be discontinued periodically.  If a corresponding discontinuation of the light amplitude modula-tion signal is sensed this is indicative of the continued presence of the flame whereas a continuation of the light amplitude modulation signal indicates a flame out condition.

Abstract: GOLF CLUB SET WITH IMPROVED OFF-CENTER IMPACT PERFORMANCE               ABSTRACT OF THE DISCLOSURE     In a set of correlated golf clubs, the heads are pro-vided with a narrowed neck (36) connecting the main body (32) of the club head to the hosel (34).  A midsection (46) of the neck has a cross section of maximum dimension less than the diameter of the hosel so that, when the main body of the club head twists under impact with a ball, the nar-rowed neck will function as a torsion bar with most of the torsion occurring in the midsection (46).  In that manner, the twisting motion of the main body is uncoupled from the hosel and shaft.

Abstract: Abstract:    A machine for sharpening the blade of an ice skate has a vertically mounted, thin grinding wheel with a convex transverse cross-section corresponding to the concave transverse cross-section desired for the blade edge.          Clamping plates on a cradle hold the blade above the wheel with their central planes coplanar and with the wheel biassed against the blade.  The cradle is pivotable about a horizontal axis above the skate so that the skate can be swung in an arc.  Hence the movement of the blade over the wheel takes place in an arc that is curved in the same direction as the convex profile of the blade edge.  This action reduces the problem of unevenness of depth of cut along the length of the blade, that has been experienced with prior machines employing straight line relative travel between the skate and the wheel.  The tendency for the wheel to take a deeper cut at the more sharply curved toe and heel portions of the blade can be further compensated for by increasing the speed of traverse of the blade over the wheel in the vicinities of these end portions.  This traversing speed can be reduced incrementally from a maximum at the extreme toe end of the blade down to a minimum over the central portion of the blade, while being increased again incrementally as the wheel approaches the heel end.  Provision is also made for stopping the motor that drives the grinding wheel when the wheel is in the area of the picks of a figure skate.

Abstract: REMOVABLE FENCE FOR TABLE SAW                         ABSTRACT A removable fence for a table saw is posi-tioned on a saw table by a locking mechanism located on the fence which simultaneously grips a pair of blocks mounted on an endless flexible cable.  The locking mechanism engages the blocks and raises them into fric-tional relation with an L-bracket mounted on the table thus preventing movement of the fence.  The blocks are affixed to the cable at points equidistant from the plane of the saw blade thereby insuring parallelism of the fence relative to the plane of the saw blade. Utilizing the flexibility of the cable which permits lateral movement, the fence is removed by releasing the locking mechanism and moving the blocks laterally away from the mechanism.
